St Valentine Day Masscre of 1929

·34 min·2 clips
Seven men were lined up in a Chicago garage and shot with Tommy guns on February 14, 1929.
The episode opens by treating the St. Valentine’s Day Massacre as one of America’s bloodiest and most stubborn mob crimes. It sets the scene in Prohibition-era Chicago, where illegal liquor traffic turned rival gangs into enemies with no shortage of firepower. Seven members of Bugs Moraine’s gang are gathered in a garage and killed after four men arrive in a police car. Two of the gunmen are wearing police uniforms, which makes the attack look like a raid right up until the shooting starts. Thompson submachine guns and a shotgun do the work. The episode does not rush past the setup or the aftermath. It stays with the horror of it, and with how fast the crime became part of American memory. The hosts stress that the massacre was never solved, and they treat that unresolved status as the point, not a footnote. The story then shifts to Fred Killer Burke, an associate of Al Capone and a figure linked to later violent crime. After a separate killing in rural Michigan, police search Burke’s house and find weapons. Calvin Goddard later tests two Tommy guns from that cache and concludes they were used in the massacre. That forensic result gives the case its famous anchor. Still, the episode does not leave the evidence alone. It keeps asking whether police involvement, evidence handling, or simple narrative convenience may have shaped the record. Burke’s movements through St. Louis, Detroit, Chicago, and rural Michigan are used to sketch the criminal world around him. The hosts keep moving between the facts and the doubts, with little patience for a clean mob-movie version of events. The result feels less like a tidy recap and more like a steady challenge to the accepted story. The episode keeps the massacre alive by refusing to treat it as settled history.
